Problems solved by technology

However, this kind of device still needs an operator to manually switch the gear of the calibration device during the calibration process, and cooperate with the operator of the smoke test system to complete the system. The whole process is not highly automated, and the calibration process lasts about 10 minutes. The calibration process is also relatively slow
On the other hand, in the process of manually switching the gears of the calibration device, the operator is likely to introduce system errors such as the slight deviation of the scale line due to personal operating factors, resulting in an increase in the error of the calibration results.

Embodiment Construction

[0044] The following examples further explain the present invention.

[0045] The present invention is an automatic calibration device for a smoke transmittance test system, which includes a sleeve 1, a reference mirror 2, a rotating mirror 3, a transmission device 4, a servo motor 5, an angle sensor 6, a control box 7, and a calibration program 8.

[0046] The sleeve 1 is made of aluminum alloy, and the surface of the shell is blackened. The sleeve 1 is in a "T" shape as a whole, the rotating mirror 3 is located in the center of the sleeve 1, and is directly opposite to the reference mirror 2 fixed at one end of the sleeve 1, and the other end of the sleeve opposite to the reference mirror 2 is an optical with good light transmission performance. glass. The servo motor 5 and the angle sensor 6 are fixed in the barrel 1 which is parallel to the mirror surface of the reference mirror 2. The rotating mirror 3 is respectively connected to the rotating shafts of the servo motor 5 and...

Abstract

The invention discloses an automatic calibration system for a smoke transmittance testing system. The automatic calibration system consists of a sleeve, a benchmark mirror, a rotating mirror, a driving device, a servo motor, an angle transducer, a control box and a calibration procedure, wherein the sleeve is in an integral T shape; an operator can set calibration parameters and automatically finish the whole calibration process through the calibration procedure installed on a computer and obtains a calibration curve and calibration parameters. The device has the advantages of high degree of automation, high calibration speed, high accuracy and the like, and can be used for quickly calibrating the smoke transmittance testing system for propellant and gun propellant combustion.

Description

Technical field [0001] The invention relates to an automatic calibration device for a smoke transmission rate test system, which is suitable for smoke transmission rate test systems such as a propellant plume smoke transmission rate test system and a propellant muzzle smoke test system. Background technique [0002] The smoke transmission rate test system is a commonly used test device in the evaluation of plume smoke performance of propellants and propellant charges. The basic principle is Lambert Bell's law. The device measures the ratio of the light intensity after the light source passes through the smoke area to the initial light intensity as the light transmittance of the smoke. In terms of implementation. Currently commonly used smoke transmission rate testing devices include propellant smoke emission-closed combustion chamber test system, propellant plume smoke transmission rate test system, propellant smoke emission test system, muzzle smoke test system, etc. Over-rate...
